Personal Pronouns in Latin
I was always taught that adding a personal pronoun like ego or nos showed emphasis to the doer of the action since the ending of the verb already tells us who is performing the verb. Be careful when learning not to engrain the pronouns into your sentences too much as it is not wrong but not necessarily correct.
Here is a website that can take the place of Tips and Notes for now if anyone has grammar questions (or I can try and help)
Edit: apparently the website decided not to show up, rendering this post pretty much useless. Here it is again :) https://latin-dictionary.net/grammar
